Redesign Accept Operation for Cross-Platform Support

Description

On Windows, the current implementation of the Accept operation in Zend Async API causes errors such as:
"Warning: stream_socket_accept(): Accept failed: The operation on a non-blocking socket cannot be completed immediately in "

This indicates that the API is unstable and platform-dependent.

Proposed Changes

1. Create a dedicated API for Zend Async API responsible for handling Accept.
2. Implement the accept operation to work consistently across all supported operating systems (Windows, Linux, BSD, macOS).
   • Account for differences in socket APIs and flags (Winsock vs POSIX).
   • Ensure unified behavior and a consistent set of error codes.

Goal

Provide a cross-platform implementation of Accept, eliminate platform-specific failures, and unify the behavior of Zend Async API.
